CONVEYER.

srncmxcncrronformin part of Letters Patent o. 523,674, dated July 31,1894.

Application filed February 9, 1894.

To all whom it may concern:

Beitknown that I, KAIETANMICHALOUSKJ, a c1t1zen of Russia, residing atMunhall, in

' the county of Allegheny and State of Pennothers skilled in the art towhich it'appertain's to make and use the same, reference being bad tothe accompanying drawings, and to the letters of reference markedthereon, which form a; part of this specification.

My invention consists of a suitable supportlng frame carrying tracks fortraction rolls or wheels, with intermediate driving rods or barsconnecting flexible endless chains, w1th carriers, buckets or traysmounted thereon: the whole opera-ted by suitable driv mg mechanism, aswill be hereinafter described.

Referring to the drawings forming a part of this specification,Figure 1. is'a'side elevat1on of the conveyor. Fig. 2. is a top'planview thereof, part-1y broken away. Figs. 3. and 4 are detail views ofthe buckets, trays or carriers.

Like letters of reference represent'like parts in the different views.

. A. is the main frame, which supports the endless chains and thecarriers or trays. It is provided with verticalstandards, B, on whichare mounted, or having secured thereto.

- by mortises or otherwise, the cross ties or bars,

conveyor, are used. Mounted on these bars,

G, and O, are longitudinal bars or beams on which are supported thetracks, D. D. at the top, and corresponding tracks, D5, D, under- SerialNo. 499,588- (No model.)

wheels, with outside peripheral fianges,.and

motion is communicated thereto by the traction wheels or rolls travelingover the peripheries' thereof. The drum, F, at the opposite 7 end of theconveyor, also consists of. two flanged wheels similar. to 'd'rum,-F,already described, but the peripheries of these wheels 7 instead ofbeing plain, are'provided with suit- Mounted onthe end of the shaft, F",is a 7 large toothed gear, H. Meshing with the gear, H, is a smallergear, H, mounted on a short shaft, H journaled in boxes secured'to thestandard or'bracket, E. On the outer end of shaft, H is a band wheel orpulley, and motion is communicated thereto by a bandor belt driven byany suitable power, as steam, electricity, or anyother motor or power,in amanne'r wellknown, and that need not be explained.

. The endless chains comprise a series of articulated links, a, pivotedto each other, and one of these chains is locatedoutside of each of thetracks D, D, D', D. In the present instance, the chains consist of 'aseries of links, scarfed or rabbeted on'op'posite sides and overlapping,and having fortheir pivots, the projecting ends of the traction wheelsor rolls. They may however, if desired, be provided with separate orindependent pivots, and any other known form of chain will answer thepurpose just as well, although I prefer the form show n'and described.Traction rolls or wheels, b, 12, mounted on the ends of suitable. shaftsor axles, connect the twoendless. chains transversely, in the manner"already explained, via, by using the ends, ofthe axles which projectoutside the wheels, as

pintles for the chain links. The traction rolls IQO to revolve, byhaving'the ends of the axles loosely mounted in the links of the chains.

The rolls or wheels revolve as they move along diminished.

Between each pair of traction rolls, that is to say, alternatingtherewith; are rods or bars, 0, which extend across, and projectlaterally beyond the outer sides of the chains and engage with theprojections or recesses, I, of the sprocket wheels on the drum, F, aswill be readily apparent. The trays, carriers or buckets lie between,and principally, are supported and carried by the chains. They eachcomprise vertical side pieces or bars, d, similar in construction to thechain links, that is, scarfed or rabbeted on opposite sides, so that the,scarfed portion of the bars of one tray or carrier shall overlap thenext adjacent one at each side, and are pivoted together.

The bottom or pillow, f, of each carrier is formed with a transverseaperture through it at one end to form a bearing, and the trays,buckets, or carriers thus constructed, are loosely mounted on the rodsor bars 0, the free end of the bottom, f, resting upon and over thebearing of the next adjacent one. The bottoms, f, are plain or flat forconveying beams, bars, 620., but if it is designed to remove and conveyearth, sand, &c., they would be in the form of scoops.

On top of the side pieces, d,of the carriers I provide lugs or flanges,g, which project in wardly, slightly over the tray or carrier bot- 1tom, f, so that as the chain is revolved, and when the trays or carriersare inverted after passing around the drum F, they will not be allowedto drop to a vertical position, so as to be in the way, or be broken01f. One or more of the trays or carriers is provided with a hinged barh, whose length is about the width of the tray or carrier. This bar ishinged preferably, at the inside and when opened across the tray orcarrier, rests against a lug or catch h, at the opposite side. Thepurpose of this bar h, is to form a stop so as to allowa beam or bar tobe set up on end, as the chains start to go around the drum F, since itis frequently desirable to have an article presented in this position sothat it may be readily grasped; by a lifting crane, for example.

It will be understood that the trays or buckets extend, ordinarily, theentire length of the chains, although it is not absolutely essentialthat they be arranged immediately adjacent to each other, since forconveying articles of great length, this would not be necessary. Thesides of the trays or carriers have a slot, to, extending from thebottom upwardly, so as to leave room for the axle or spindle of thetraction rolls.

When the hinged bar It, is not needed, it can be neatly folded or shutup against the side of the tray or carrier and be wholly out of the way.

It will be understood that the conveyor may be of any desired length,according to the distance to which the materials or substances are to beconveyed or I transported, and I do not limit its use to the conveyingof any article or substance.

If the conveyor should be of great length, or if for any other reason itshould be found desirable, as for example, if an electro-motor should beused; gears similar to those on drum F, are applied in the same mannerto drum F, and in this construction the driving band or belt would becarried around both band wheels or pulleys, and suitable idlers and abelt shifter may be used.

The operation of myconveyer will be easily understood from the abovedescription, 1n connection with the drawings.

The article or substance to be conveyed is supported or held on thetrays or carriers; motion is communicated by power applied through thedrawing belt, gears and sprockets; the chains and traction wheels orrolls, with the carriers are moved along on the tracks in the directionof the arrow, and the articles or substances are conveyed to" any desired place.

For convenience in loading or unloading the conveyer, I use a series ofrolls mounted in a frame and suitably supported; at one or both ends ofthe conveyer, as shown at R.

The bars or rods 0, may be round, square, or of any other suitable formin cross section.

The chains and carriers may be arranged to travel horizontally as shown,or they may be arranged vertically, or even at an angle to the horizon.

The size and proportions of my conveyor, as well as certain details instructure may be changed or modified within the scope of my invention,and I reserve the right to make such changes.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. In a conveyer, a pair ofendless articulated chains, a series of axes or journals with tractionrolls or wheels mounted thereon, said axes or journals forming pivotsfor the chain links 5 suitable tracks for the wheels or rolls; trays orcarriers mounted between the chains, aseries of sprocket barsalternating with the axes of the rolls and forming pivots for the sidesof the trays or carriers and separate bottoms for said carriersjournaled on the sprocket bars, and suitable driving mechanism,substantially as set forth.

2. In a conveyor, a pair of endless articulated chains connected-to eachother, transplates, and independent bottom plates pro:

vided with a transverse bearing mounted on the sprocket bars, the freeend of each bot tom plate or pillow resting upon and over the bearingsof the next adjacent plate, and suitable driving mechanism,substantially as de'-" scribed.

3. In a conveyor, aseries of trays, buckets or carriers each havingseparate vertical side plates and an independent bottom plate, thelatter having a bea'ringat one end, and a journal on .which the bottomplate is pivoted, the other end of the bottom plate being free andresting upon and'over' the bearing of the next adjacent bottom plate,substantially as set forth. 7

4. In a conveyor, a seriesof trays, buckets or carriers each havingseparate vertical side plates, inwardly projecting plates or flanges,and an independent bottom plate having a bearing at one end, and ajournal or axle on which the bottom plate is pivoted, the other I end ofthe plate being free and resting upon and over the bearing of the nextadjacent bottom plate substantially as set forth.

5. In a conveyor, a series of trays, buckets or carriers, each havingvertical side plates or bars and pivoted bottom plate; one or more ofsaid trays or -carriers being provided-with a hinged or pivoted baradapted to be swung across the bottom from one side, and rest against alug, on the opposite side, substantially as set forth, In testimonywhereof I affix my signature in presence of two-witnesses 7 I KAIETANMIGHALOUSKJ.
